Okay...double-checking the docs.python.org writeup, it apparently
does "work across platforms" (Mac & Unix), just not "across *all*
platforms", with Win32 being the obvious outlier. It seems a
strange omission from Win32 python, even if it were filled in
with only a stub...something like
def samefile(f1, f2):
return abspath(f1.lower()) == abspath(f2.lower())
it might not so gracefully handle UNC-named files, or SUBST'ed
file-paths, but at least it provides an attempt at providing the
functionality on win32. As it currently stands, it would be
entirely too easy for a [Mac|*nix] programmer to see that there's
a samefile() function available, use it successfully based on its
docstring, only to have it throw an exception or silently fail
when run on win32.
